电荷和质量对高维旋转黑洞蒸发的影响

Charge and mass effects on the evaporation of higher-dimensional rotating black holes

Marco O. P. Sampaio

摘要:

为了研究TeV引力场下膜黑洞放电的动力学,通过微扰求解膜上的Maxwell方程,得到了带电黑洞放电的近似电磁场.此外,参数给出了膜度规修正由于反作用。我们将具有非零质量和电荷的膜标量场和膜费米子场耦合到背景中,利用已知的低能近似和高能极限下的WKB近似研究了霍金辐射过程.我们认为,相反,共同的索赔,初始蒸发并不占主导地位的快速Schwinger放电。

英文摘要:

To study the dynamics of discharge of a brane black hole in TeV gravity scenarios, we obtain the approximate electromagnetic field due to the charged black hole, by solving Maxwell's equations perturbatively on the brane. In addition, arguments are given for brane metric corrections due to backreaction. We couple brane scalar and brane fermion fields with non-zero mass and charge to the background, and study the Hawking radiation process using well known low energy approximations as well as a WKB approximation in the high energy limit. We argue that contrary to common claims, the initial evaporation is not dominated by fast Schwinger discharge.
